Required torque for Halton UTT-damper actuator

Function

The Halton UTT dampers are used to shut off or control airflow in ductwork where tightness, thermal insulation and reliability are important.
In the closed position the Halton UTT damper leakage class is 3 in accordance with the EN1751 standard.
In the open position the blades are turned in the direction of flow and do not cause significant pressure losses.

Damper sizes conform with the international standards EN 1505, EN1506 and ISO 1707 for rectangular and circular ducts.

The maximum operation temperature of a standard damper is +100°C (for optional models +200°C).

Heat transmission of the damper is 6 W/(m 2 K).
 

Installation

Code description
1.  Casing
2 . Blade
3.  Gaskets
4.  Manual adjustment handle / actuator platform

Install the damper in the ductwork with the blades in horisontal or vertical position.
Fasten the damper in the ductwork using slip joints.

Optional models enable fastening the damper to duct flange by using bolts.
Drill holes in the damper flange if necessary (options L1 & L2).
Use a seal between the flanges in order to tighten the seam.

Fasten the models with circular connections by riveting or screwing.

Specification

The casing and blades are made from galvanised steel or stainless steel AISI 316).
The blade gaskets are made of silicon (or EPDM- rubber).
The drive shaft socket is made of galvanised steel with self-lubricating slide bearings.
The bearing is made from an alloy of polyamide and molybdenum sulphide (or stainless steel AISI 316 or stainless steel AISI 304 or bronze).

The damper is installed into rectangular ducts in compliance with EN 1751, or in circular ducts D=100 ...1250mm in accordance with EN 1751.
The damper meets the tightness requirements of EN 1751 class 3.
The casing of the damper meets the tightness requirements of EN 1751 class B.

Heat transmission of the damper does not exceed 6 W/(m2K).
The damper is suitable for either manual adjustment or actuator operation.
